Warp drawing machine of the general type shown in United States Patent No. 980,086 and British Patent No. 958 of 1907 Such application or the invention is herein shown for illustrative purposes only, the pattern mechanism illustrated having adaptation to machines employed for other purposes as Well as to Warp drawing machines oi. other types than the one herein shown;

In the disclosed type of drawing in ma chine, the principal parts of the operating mechanism only are shown (Figs. 1 and 2). In this type of machine there is provided a bed 1 upon which are appropriately supported (but not .SlTOWIl) the Warpthreads,

(eight in number in the machine shown in Figs. 1 and 2).' These rods extend length- Wise the machine and act to select and feed, according to predetermined arrangement, the Warp threads, reed dents and harness eyes with reference to the path of the drawing needle. The thread separatingrod t (the outer one of the series) carries at its end adjacent the needle path suitable thread separating-.devices'which under each tull rota-- tion of the rod present the next ivarp thread to the action of the drawing-in needle. Another of therods at the opposite end. of theseries (Fig. 1) is connected toa suitable reed opener device which also, under a full rotation of the said shaft, spreads and opens the. reed splits. The remaining and intervening shafts 6 pass to their respective separating and "feeding devices for the chine illustrated, are supposed to be six in number arranged in sets oftivo each. or each semi-revolution oi aharness separator shaft, an eye of its respective harness is presented Within the path of the drawingin successive H threads several harnesses which latter, in the ma pin 13 the latter with the plunger being movable lengthwise of the shaft 8 in a slot therein so that in its retracted position it may be seated within a notch let in the sta tionary sleeve 10 or inits projected position (shown in Fig. 7) it may be seated within a notch 15 formed in the hub of the gear or other driving member 16 which latter is loosely mounted upon the operating shaft 8.

From this it follows that with the plunger and its clutch pin retracted, the operating shaft and its rodare held positively fixed. lVith the plunger rod projected and its clutch pin seated in the notch 15, the op-' erating shaft is clutched to the gear 16 and partalres of the same movement with the gear. This construction, except for the proportion or form of the driving member 16, is substantially the same with reference to each of the shafts 4, 5 and 6, referred to. By means of driving connections from the main driving shaft 17, the details of which connections form no essential part of the present invention, the several driving members 16 have imparted to them movements appropriate for turning their respective, operating shafts.

To this end, th warp separating shaft 4 is given a constant rotation at the rate of one complete revolution for each reciprocation of the drawing needle, the driving members for the harness shafts 6 being turned intermittently a semi-revolution for each reciprocation of the needle and the driving member for the reed'shaft being turned a 'full revolution for each needle reciprocation. The clutch devices are thereby selectively operated in predetermined pattern arrangement and any desired sequence of operations with the various operating shafts may be had. This provides for the selection and presentation of a heddle eye from one harness followed by the presentation of an eye from any other desired one of the six harnesses and the operation of the reed dent opener and warp separator either with reference to successive thread drawings or semi-occasionally only, as may be desired.

In the described embodiment of my invention, I have provided means for actuating the plunger shaft 12 for the several clutches as follows: For the series of garners plunger shafts there is provided a common reciprocatory actuating member herein consisting of the plate or casting 18 provided with a series of cars 19, adjacent pairs of which are adapted to engage each a collar 20 on the plunger shaft 12 (see Figs. 5 to T inclusive). The actuating plate has a jour naled support at 21 in the carriage frame to permit of a rocking movement about its axis, an oscillatory movement being imparted thereto by means of the face cam which engages a cam roll 23 carried upon an arm 2 f depending from the plate. This serves to give a quick movement forward and then backward to the actuating plate for each reciprocation of the needle. The cam 22 is mounted upon the same shaft with a gear 25 (see Figs. 1 and 2) driven through intermediate gears 26 and 27, from the main driving shaft of the machine. As the plate rocked forward it ad *ances each collar 20 with-its plunger shaft and clutches the corresponding driving member to its operating shaft causing the operating shaft to partake of the movement of the driving member which immediately follows unless the plunger is meanwhile retrzu-ted. The plunger shaft is retracted by means of the spring 28 interposed between the end of the shaft 8 and collar 20. With each forward movement of the actuator the several driving members are clutched to their respective shaft, the same, however, being immediately released unless held in active position by the feeler devices herein described.

To prevent retraction of the plunger rod for any given clutch and thereby select for operation its corresponding ()POIftltillg shal'l. during the next cycle of needle movemlmt, feeler members are employed which. under the control of a suitable pattern device, present, at the appro iriate time and behind the appropriate plunger rods, obstrmztions or abutments preventii'ig the retraction of the rods.

This may be accomplished in various ways but herein a fixed rectangular frame is pro vidcd at the end of the carriage lamsisting of two frame members H). and Elf}. extending transversely of the machine and the frame members Llel: and 35 (i l and 53) extending longitudinally of the frame. The frame member 32 (Figs. l and i') acts as a war guide for the ends of the sliding plunger rods 12 while the meii'ibcrs ll and llf) slidably support and guide a si 10:; of leeler bars 236, one for each plunger rod, each i'eelcr bar carrying an abutment cons :liugr of an upright pin or finge lwlach rod Willi its abutment linger executes a limited movement transversely the axis of its plunger rod so that, as required. the abutment linger may be interposed bacl: of the advanclnl plunger rod and prevent its warm-lion.

Those teeler bars 'WlllCli register with an unpertorated .iortion 01: the )attern sheet however are held back by the latter in an inactive or clutcl'i-ri-ileasingg ')0Sii JIlOIl. YVhen the pattern actuating. sleeve 11 i undergoes its next movement, the beveled shaped teeth 48 posi: tively torce or wedge the healer bars back by pressure against the beveled ends thereof,

each of the latter being thereafter held back by the pattern sheet until a pertoration therein is brought to register With the end of the bar. The iitlcltll'l member i-i' may or may not act a limiting stop tor any selected iteeler bar which pei'ietrates the patteri'i iil'lQt-lt. Preterably, however, it acts as described as a pee Jive actuator tor moving bach. the i'celer bar, relieving the pattern sheet oi any undue ineciu'uiical strain thereof. The pattern sheet an tl'iereiore be made relatively ligljlt and thin. and suitably peri OJ'ZttBtl paper sheets may be used tor this purpose.

To niovethe pattern sheet fleshy-step in synchronism with the needle reciprocations, there is provided a can: (see Figs. 5 and (5) attached to the hub oi the taco cam "lhis cam is provided with projections which engage the cam. roll 56 carried by the depending; arm 57 on the sleeve 58, the latter (Figs. 5 and ti) inoruited to oscillate on the tired shaft kit). The sleeve 58 a t one side is provided with a drum shaped meinberhii (Fig. 1i) which erurases a ratchet Wheel 60, the latter pinned to the :uljacent pattern actuatiire'slecve a-l. The drum member 59 carries a spriiigprcssml pawl 6i engaging the teeth of the ratchet and so arrang'ei'l that when the arm 56 is lifted by the rain. 55 the pawl en- .tt'anes the teeth oi the ratchet ainl moves the through one step which is equivalent to the presentation oi a tresh transverse set of pattern peri'orations to the :teeler bars.

The earns 22 and 55 are so proportioned tlat at each renraction ot the drawing-in needle. the clutch actuator 18 is innnedh atelv thrown forward and the pattern sheet simi'iltaneouslv advanced one step, the selectone step, those Fig. to enter the correspoiiding underl v lat er with the actuating sleeve cross supports 76 and 71 on which hind their respective selected rods before the retraction. of the clutch actuator 18, which immediately thereafter takes place.

The cam roll 56 is held against the cam and the pawl 61 is reversed by a tension spring 63 connected to a lug 64 on the drum. 59.

The pattern sheet may be in the form of an endless belt, the same pattern being drawn and redrawn in continued succession. lVhen a pattern sheet of this description is employed (see Fig. 2), the same being herein shown as journaled upon the shaft 66, the latter carried by the upright arm 67 is adapted to be clamped in different positions of angular adjustment on the block 68 to adapt the position or the roller to pattern sheets of different lengths.

l/Vhere a longer pattern sheet is required than it is convenient to mount upon the single guide roller 65, a plurality of guide rollers may be employed mounted upon a suitable frame such as is shown in Fig. 2. Therein an arm or upright 69 is supported in the block 68 and carries upper and lower are journaled a succession of guide rollers over which the elongated pattern sheet "(2 passes in its travel. By increasing the number of these guide rolls a pattern sheet of any re quired length'may be employed.

In the case of simple patterns or under other conditions it may be desirable to employ a pattern member of cylindrical or roll form in place of the member in sheet form. In Figs. 9 to 15, inclusive, I have shown the details of such cylindrical pat ern member, the same being so constructed that it may be adjusted to produce any required pattern. In the form illustrated twelve successive dite ferent combinations may be ellected in the movements oi? the operating shafts before a repetition is necessary, but the number oi such operations, or in other words, the length of the pattern, may be increased by increasing the diameter of the cylinder.

its indicated in Fig. 10, the construction of the cylindrical pattern member is similar to that of the pattern actuating member shown in Fig. 8, except that for the backing member i? there is substituted a plurality of pattern elements, each consisting of a washer 73, there being provided one washer or pattern element for each :l eeler bar, these being herein in connection with intervening blank or separating washers 74. The blank washer is shown in Fig. 12 and different forms of the pattern washers are shown in Figs. 13, l t and 15. It will be seen that the pattern washers are similar to the blank washers except for the notches cut in the periphery at various points, the notches performing the functions of the perforations in the pattern sheet 40. By arranging diflerout forms of these washers in different angular positions on the sleeve the notches or recesses may be arranged to provide any desired pattern control as in the case of the pattern sheet.

Any suitable means for adjustably lixing the washers upon the sleeve may be employed, but preferably an arrangement is provided whereby each washer may be shi l'ted to any one of the twelve or other possible angular positions upon the sleeve and in that position may be positively driven from the sleeve itself. To provide for this I have caused each washer to be drilled with a series of holes 75, herein twelve in number corresponding to the twelve positions of the pattern member as it is turned in its step-bystep movement. With each pattern washer adjusted to its desired angular position on the sleeve one or more wires or small rods 76 are then inserted through the holes 7 5 in the series of washers, .whirh holes are thus brought into alignment, the rods or wires being seated in a corresponding hole in the enlarged end of the fixed sleeve ate; and also in the collar 45 at the outer end of the sleeve. This provides "for the positive driving of each individual pattern member directly from the actuating sleeve itself, while at the same time it permits the adjustn'ient oil the pattern washers at any desired time to dil lerent angular positions. It also permits them to be withdrawn and washers of different form substituted.

It is sometimes required to shi'lt or clnmge the pattern, either temporarily or at some given time in the operation oi the machine or under other conditions which make it impracticable or inconvenient to replace the pattern sheet by another. This may be desirable, for example, in the case of a drawing-in machine for drawing the selvage at the beginning and end of the drawing-in operation. To accomplish this I have provided means for shifting the entire pattern device laterally so that a different set of pattern perforations or depressions may be quickly brought at any time into ulignn'icnt with the teeler bars temporarily withdrawing from registration with the fender bars the prior set of pattern perforations. For this purpose the longitudinal rows of pattern perforations are so spaced in the pattern sheet 4:0 as to permit the formation of intermediate rows of pattern perforations.

In the form shown in Fig. 1, for example, the first row of such auxiliary pattern per forations would occur between the inner row of sprocket teeth perforations and the first or continuous row of main perforations and each successive row of auxiliary pattern perforations would be positioned between each two successive rows of main pattern perforations. In the case of the cylindrical pattern member shown in Fig. 10, such auxiliary pattern member could be provided by sub- All minors stituting pattern washers for l the blank washers let in the pmsitions where suchmblanlr washers are shown emailed to the pattern and bring grooves 77 and 78 in which tliere is adapted pressed h n ger to seat a downwardly spring 79 (see Fig. l) pivoted on the .iame mem ber When the finger "f9 is seatedin the outer groove 78, the pattern member ismaintained laterally "in the position shown in Fig. 1. By lifting the finger 79 however, the pattern member may be slid outwardly and the finger dropped into the groove 7'7, whereupon auxiliary pattern perforations which may be provided intermediate the main pattern perforations, are liirornrghtinto registration with the 'teelerbars.

i The operation of thecontrolled mechanism will be readily understood i'trrun the precedinn description. l 'Vith each retraciztiou of the drawing-in needle the several clutches are thrown into engagement by the common ac tuator 18, but immediately released un less held against release by the interposition of an abutment- 517 in the path of the corresponding plunger rod 12. For each clutch there is a correspondingmovable abutment 3'? and a corresponding teeler bar 36. Each feeler bar is norniially held with its abutment at one side of the rectilinearly movable plun r rod, but on the presentation ot the per "0 tion to the end otthe 'teelcr bar thelatter [5; moved by its spring 38 and enters the pertoration of the pattern member bringing the corresponding abutment directly within the path of the clutch rod 12 so that the corresponding clutch remains engaged and its sha'ii'ttl'iereupon turned,

i In the case of the harness eye separator shafts, perforations are usually provided in eding pairs, so as to provide for halt turn of the separating shaft following the retraction of the needle to face an eye, tel lowedby a second half turn to pass the eye along: after the next retraction of the needle. In the case ot the warp thread separating shaft 4-, there is ordinarily provideda pattern perforation torfleach needle movement, except when it desired to stop the movement of the shalttto drop a thread. in the case of the reed opener shalt perforations are ordinarily provided for eaclralternate t iread movement this resulting in drawing two threads throunheach reed dent. This jmtion with the :teeler bars the ward ends order can be varied in any desired manner so as to provide for any desired. succession of thread, reed-dent, or harness eye selectingand presenting movements.

lit will be seen that themechanical work of throwing in and out the clutches is perl liilil'Kflllly actuating; devices apart from. the pattern. selective mechanisms, the pattern controllii'lp; devices performing 110 Work in and ot' themselves except to control the reciprocations oi thevlight feeler bars.

lVhile the abutments 37 might be made of 'l' :ient length to hold the plunger rods 12 1st retraction in and of themselves, preferably"those movable abutinents are merely interposed between suitably positioned fixed abutn'lents 82 carried by the trains member 33, such abutments comprisinn bars projecting each from the said frame ntienlber in alignment with a plunger rod and relievingthe abutinents 37 and the :teeler bars from: any undue strain.

in, order to withdraw all the feeler bars simultaneously from the pattern member in orderto start at a "fresh point on the pattern or replace the old pattern with another, the ends of the bars are notched at 83, as shown. 1 and 4:, and the cap piece provided with a downward shoulder 84; resting in the notches on the bars. The cap piece is held to the underlying frame member .5 by means of studs passing through slots 86 in thecap piece so that the latter may he slid back when desired by the knob 87 to with draw all the iteeler bars from the surface of the pattern sheet. ll desired the shoulder 84; may be utilized to limit the forward l'llOVGlllQlll} of the feeler bars when their for enter the perforations of the pattern sheet.

llhile l have herein shown and described for purposes of illustration one specific form of the invention, it is to be understood thatdzhe same is submitted. tor illustrative purposes only and that extensive deviations maybe made from the details of construe tion, location and relative arrangement of parts andthe application made of the invention. without departing from the spirit thereof.
